API tContains

tContains(table, value)

Returns true (1) if value is in table, false (nil) otherwise. Note: this is not a standard Lua function, but was added by Blizzard to simplify table searches.

Implementation

function tContains(table, item)
       local index = 1;
       while table[index] do
               if ( item == table[index] ) then
                       return 1;
               end
               index = index + 1;
       end
       return nil;
end

Example Edit

banana = { "yellow", "curved", "yummy" };
lotus = { "pink", "pretty" };

eatme = tContains( lotus, "yummy" );

Result

eatme = false
